Glacial Flooding: Another Threat of Global Warming

Dear readers .Here is another interesting reblogged post.Enjoy.

Glacial Flooding: Another Threat of Global Warming For years, I had heard about how glacier melting caused by global warming was imperiling the world’s fresh water supplies, the vast majority of which come from mountains. But I hadn’t thought about the flooding threat the rapid melting poses to mountain communities until I listened to presentations by mountain geographer Alton Byers and Nepalese mountaineers Apa Sherpa and Dawa Steven Sherpa last week in Italy. A quick search of the Internet, pro … Read More

Chinese Scientists Teleport Information 10 Miles

A new report by Chinese scientists shows that it is possible to transmit information over long distances using quantum entanglement. The research, published in the current issue of the journal Nature Photonics, could lead to faster and smaller quantum-based computers and unbreakable, encrypted communication across the world.

China’s 4th satellite launched to boost its global navigation network

China successfully launched its fourth orbiter into space at 23:53 Wednesday, as a part of its indigenous satellite navigation and positioning network known as Beidou, or Compass system.

The launch was disclosed by the Ministry of Industry and Information Technology via a statement posted on its official website Thursday.

The satellite was launched from the Long March 3III carrier rocket.

It will join another three satellites in orbit to form a network that will eventually consist of 35 satellites, said the statement.

According to the plan, the system will provide navigation, time and short message services in the Asia and Pacific region around 2012. It will be capable of providing global navigation services by 2020.

China started to build up its own satellite navigation system to break its dependence on the U.S. GPS in 2000, when it sent two orbiters as a double-satellite experimental positioning system, known as the Beidou system.

Yangtze River’s Ancient Origins

The Yangtze River in China is 40 million years older than was previously thought, according to new research.A study of minerals by a team led by Durham University reveals that the Yangtze River began to cut the Three Gorges area around 45 million years ago, making it much older than previously believed.

The Yangtze River, the third-longest river in the world, has played a central role in the development of Chinese culture, and the Three Gorges, which separate the Sichuan Basin in the west from the lowlands of central and eastern China to the east, have particular historical, cultural, and geomorphological significance.

Without the transport pathway created by the Three Gorges, south-western China — including the rich agricultural area of Sichuan Province, known as China’s ‘rice bowl’ — would have remained cut off from the rest of the country by the otherwise inaccessible mountains that surround the region.
